Brake Pedal Travel; Brake Adjustment - GMC T-Series 1999 Owner's Manual

Brake Pedal Travel

See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.

Brake Adjustment

Every time you make a brake stop, your brakes adjust
for wear.
Air Brake Systems (If Equipped)
If you have air brakes, it is important to get rid of
moisture in the system. Moisture will damage your
system if it isn't removed daily.
There are two ways to do this. One is automatic if your
-
air brake vehicle has the optional moisture ejector. If
your vehicle doesn't have that option, however, you
must drain the air reservoirs every day.

Moisture Ejector (Option)
If you have air brakes with a moisture ejector, the valve
automatically ejects moisture from the reserve tank
when the air compressor cycles.
Drain them at full system
pressure. To be sure you're
at full pressure, check your
air pressure gage. It should
read at least 100 psi
(692 kPa).
